by which it may be conveniently operated. By shifting the clutch theshaft 7 and gear 14 may be driven for the purpose of operatin themachine.

gfiivoted on the shaft 7 is the bracket 15 having the studs 16 and 17thereon on which are mounted to rotate the gears 18 and 19. The gear 18meshes with the gear 14 and the gear 19 meshes in turn with the gear 18.The plate 15 is clamped in position against the bar 4 by means of themachine screw 20. The gear 18 moves with the bracket 15 radial to thegear 14 and remainsin mesh therewith and the gear 19 moves toward andawe from the gear 21 which is keyed to the she t 22, which shaft issupported on the carriage 80 which will presently be described.

A bar 23 is provided having vertical slots therein through which extendsmachine screws 24, 25, 26 and 27 bv which it is clamped to the side bar4. Riveted to the bar 23 is the bar 28. Passing through the bar 4arethethnmb screws 29 and 30 which are threaded in the bar 4' and theends of which bear against the bar 28. The bar 23 may be released byloosening the machine Screws 24, 25, 26 and 27 after which the bar maybe raised or lowered turning the thumb screws 29 and 30 unti the bar 28is in the desired position after which the machine screws 24, etc, maybe tightened up clamping the bars 28 and 28 in position. This adjustmentis necessary in adapting the machine to working on boxes or ack 5 ofdifferent thicknesses as'will be present y described.

On these bars 23 and 28 is supported the magazine in which the labelsare carried, a selecting mechanism by which they are fed one at a timefrom the-magazine, the paste be; and the oolti device by which the pasteis taken fromthe 1 aste box and applied tothe tahelsyand he mechanism bywhich the'lnbel is'final iy placed and heldi'n pontion for applicationto the box or pack- All the? for cling parts are raised or lowered inthe justinent ofthe bars 23 The hopper which carries the boxes orpackagesais not supportedby the bars 23 and 28 and is not disturbed' byan adjustment thereof. i r

Mounted on the bars 23 and 28 are crossbars 31,32,28 and 84. Mounted onthe bairs4and 5 are'the cross bars SB-asid 3'6 extending between whiehbars and snpperted by them arethe bars'37, 38, 39 -and which run thelength of the inachine and support the paokagesas'the passthreugh the mmchine from the h r at one end ng the othen end. -The-cross barfi is alsosupperted by the-bms 4 and 5 and in tiirn the bare supports the bracket41 on which in turn is supported thefree end of the cross bar 42', theopposite end of which issiipportedby the bar 5. It will be understood bythis that the bar 42 does not extend across to the bar 41ml; tops shortof the bar4 and bars 23 and 28 to permit the vertical independentadjustment of the bars 23 and 28 without interference with the bar 42.The bars 37, 38, 39 and 40 are supported by and fastened to cross bar 42and from the cross bar 42 to the right in Fig. 8 to the cross bar 35extends a bar 43 filling the intervals between the bars 38 and 39, thebar 38, 43 and 39 making a continuous platform which supports therevenue stamp and presses it against the ackage as the package movesalong throug the machine.

Fastened to the underside of the cross bars 31, 32, 33 and 34 are thebars 44, 45, and 46 between which and the bars 37, 38, 39 and 40 to thepackages are guided through the machine. The bars 37, 38, 39 and 40 runsubstantially the full'length of the machine while the bars 44, 45 and46' start with the bar 81 at the forward end of the hopper and runsubstantially the full length of the machine. Fastened to the bar 4 'isthe upright 47 and fastened to the bar 5 is the upright 48. Betweenthese two upright-s extend the cros pieces 49 and 50130 which in turnare fasteflied the upright angles 51, 52, 53 and 54 which constitutethehoppcr'for the boxes, these uprights being fastened to the cross pieces49 and 50 as follows:

A bracket 55 is provided with a lug therein that extends between thebars 49 and 50 and throu h this bracket and through this lug exten s apin 56 having a reduced threaded end that is engaged by the nut 57 andwasher 58 b which the pin 56 and bracket 55 are adjustably clamped inplace on the cross bars 49end 50, The upright 52 is fastened to thebracket 55 and moves therewith. To the bottom of the bracket 55 isfastened the fprwerd end of the guide bar which guide bar bears againstthe side or edge of each of the package as they move through the machineand hold the packages to the proper line of travel. A bracket 60 similarto the bracket 55 is in like manner fastened to the cross bars 49 and 50and at the bottomthereof is in like manner so rted the forward end ofthe bar 61 Wh 0 like the bar 59 bears against the opposite side of eachof the ackages and holds them to the direct line 0 travel. The rear endof the bar59 is rovided with a pill 214 that extends lateral ytherefrom. A post 215 tothe bar 4. This 0st has an opening therein.that'is adapts to receive 'thepin 214 and a screw 216 is provided withwhich the pin 214 and bar 49 may be fastened in an desired adjustment.(Paths bar fil a pin 21 i provided which in like manner-engages with apost 218 fastened on theba'r'li a screw' 2i'9 cla s it inv the post inthe des red adjustmehti ythis device the side bars 59 and 61 may beclamped at the rear end to correspond with their setting in the hopperat the forward end of the machine.

Mounted on the pin 56 is the bracket 62, this bracket being adjustablethereon and held in place by the set screw 63. A similar bracket 64' ismounted on the pin 65 and is held in place by the set screw 66. Thesebrackets support the angles 53 and 5d and are adjustable along the pins56 and 65 to vary the length of the hopper and the brackets 55 and 69are adjustable toward and away from each other on the cross bars 49 and50 to vary the width of the hopper, to accommodate the hopper to thedifferent sizes of the boxes that the machine may be called upon fromtime to time to handle. The brackets 62 and 64 have at the bottomthereof a sliding engagement with the bars 59 and 61 by which engagementthe brackets and angles are heldin an upright position.

: A's-shown in Fig. 7 the ends of the bars 44, 45 and 46 are upturnedand engage with recesses in the bars 50 and make a sliding engagementtherewith so that as the bars 23 and 28 are raised and lowered the bars14, 45 and 46 will make constant engagement with the cross bar 50 asthey rise and fall with the bars 23 and 28. As shown in Fig. 7 theupturned ends of the bars 15, etc, are won tersunk into the cross bar59.

' Mounted to rotate between the bars is the shaft 67 on which is keyedthe sprocket wheels 68 and 69 on which travel the sprocket chains 12 and13. The sprocket wheels 68 and 69 are separated by a collar 72 placed onthe shaft 67 spacing them apart, this collar having an annular recesssunk therein. From this annular recess extends forward a guide orsupporting bar 73 with which engage the tails 74 of the dogs 7 5 thatare carried between the chains 12 and 13. These dogs are upturned at theforward end and are provided with fingers that extend up between theguide bars 37, 38, 39 and 40 and are adapted to engage with the bottompackage ofthe hopper and push it forwardly out of the hopper and throughthe machine between the upper and lower sets of guide bars and the sidebars heretofore described. The bar 73 is supported from the bar 5 bymeans of the brackets 76 and 77. The dogs are shown in perspective inFig. 6. As the dogs are carried forward by the chain the tails 74 of thedogs will act on the bar 73 and hold the fingers in an upright positionand this position is maintained until the. tail. of the dog pames beyondthe forward end of the bar. 73 at whichpoint or shortly thereafter thefingers engage with the cross bar 42 causing the dog to swing to theposition shownin Fig. 8 permitting it to pass under thecrossbar. Thesprocket chains 12 and 13 at their forward ends pass around the sprocketwheels 10 and 11 which are separated by a collar similar to the collar72 which separates the sprocket wheels 68 and 69.

The operation of the sprocket chains and their dogs is to carry thepackages from the hopper forward with regular intervals be tween thepackages as is shown in Fig. 8, the packages being left by the sprocketchain at the point where the dogs disen gage therefrom just after thelabel has been atlix'cd thereto, after which the succeeding packagepushes against the precedin -package which packages make a coutinrmusrow, the last package when it is pushed forward by the conveyor at theleft end of Fig. 8 causes the first package at the right end to bepushed out of the machine.

Supported on the cross bars 32 and 33 is the carriage 80 which carriagecomprises the upright plates 81 and 82 which plates are spaced apart bythe shouldered bolts 83 and 84. Mounted to rotate in the upright plates81 and 82 is the shaft 22 which carries the gear 21 heretofore describedwhich gear is on the outside of the plate, the shaft 22 extendingthrough the plate. This shaft is the driving shaft for the label feedingand pasting mechanism.

Between the two plates on the shaft 22 is carried the gear 85 and thecam 86 both of which are keyed to the shaft and rotate therewith. Thecam 86 is grooved for driving the suction pump 88, which pump issupported by a plate 87 mounted on the upright plates 81 and 82. Thispump has a piston 89 therein which is driven in one direction by the cam86 and in the other direction by the spring 90. The piston. is formedwith a cup 91 having. an opening therein through which the reduced endof the piston rod 92 extends. the piston rod having a shoulder thatcompletely covers and closes the opening. A round block 93 is providedin the piston with which the thread- 1 10 ed end ofthe piston rod 92engages and by which engagement the piston rod 92, the piston 91 andblock 93 are all securely fastened together. An annular opening is leftbetween the block 93 and the piston 91 in which the spring 90 engages.The block 93 is usednot only to hold the spring in place but also toreduce the clearance. so that as the piston is driven forward by thespring it will produce suction and make a strong vacuum. An opening 9 1provided in the plate 87 so that the air may pass in and out asthepistonoperates. On top of the cylin der of the pump 88 is a dome 95 which hasan] opening therein with which communicatesa tube 96 by which thesuction of the pump is transmitted to the pneumatic selecting devicethat will presently be described.

LMounted to rotate continuously between the plates 81 and 82 are theshafts 97, 98, 99, 100, 101, 102 and 103. Also mounted between theseplates is the shaft 104 which rotates intermittently. Also mountedbetween these plates are the shafts 105 and 106 which have a rockingmotion. The shafts 97 98, 101, 100 and 104 all extend outside of theplate 82 as appears in Figs. 2 and 1.

()n the shaft 104 is the rubber coated feed roller 107 which feeds thefirst or end label from the magazine. On the shafts 100 and 101 are thesolid metal rollers 108 and 109 which grip the label and pass itdownward. As appears in Fig. 4 the roller 108 is firmly but yieldinglypressed against the roller 109 by a spring so as to exert a uniformpressure on the label that is fed between them.

On the shaft 98 is the grooved roller 110 which presses the labelagainst the corresponding grooved glue roller 111 shown in Figs. 5 and21, the details of which will presently be described. 011 the shaft 97is the grooved feeding and supporting roller 112 which roller operatesto hold the label in position so that it will make suitable contact withthe box and then press the label against the box as the box passesthereunder with the label. Mounted on the cross bar is the bracket 113on which is formed a yoke 114 in which is journaled a grooved pressingroller 115. This roller rotates in boxes 116 which boxes are mounted toslide in suitable recesses provided therefor in the ends of the yoke.This roller 115 is driven by frictional contact with the roller 112 orwith the label that passes between the two rollers. The roller 115 isevenly pressed forward by the springs 117 provided therefor in therecesses of the yoke. The collars formed on the roller 115 will occurout of line with the collars on the roller 111 so that the collars onroller 115 will not make contact with the pasted surface of the label,it being understood that the roller 111 will apply the paste to thelabel in narrow lines leaving dry strips on the label between said linesand it is with these dry strips on the label that the collars on theroller 115 make contact.

The roller 112 is grooved with three grooves for a purpose that will nowbe exlained. Mounted back of the roller is a block 118 which block issupported from the bracket 119 fastened to the upright plate 82. At theforward end of this block project three fingers which fingers extendclear through the grooves of the roller 112 on the underside thereof,the purpose of these fingers being to strip the label from the roller incase the label adheres to the roller and thereby prevents the label fromfollowing the roller around. This holds the label in such a position asto assure the adhesion of the label to the package as it passes underthe roller and under the block 118.

These fingers are formed preferably so as to extend along the under sideof the block. Pivotally fastened to the block 118 is a block 120 towhich is connected the spring pressing blade 121 under which the labelor stamp passes as the package moves rearwardly in the machine b whichspring the label is yieldingly pressed against the package. The pressureof this sprin is reinforced by the spring 122 and 123, t 1e spring 122being supported from cross bar 33 and the spring 123 being supportedfrom the cross bar 34. Blocks 124: and 125 are rigidly supported onthese cross bars each of which blocks supports an adjusting screw 126and 127, which screw is adapted to bear against the springs 122 and 123and vary the pressure that is exerted by the main spring 121 on thelabel as it passes thereunder with the box. Carried on the bars 4-1, 45and 46 between the cross bars 31 and 32 is the paste box 128, which boxhas the shafts 129, 130-and.131 mounted to rotate inside thereof. On theright hand end of these shafts, as shown in Fig. 5, are placed thedriving gears 132, 133 and 134. Mounted on the shaft 129 is the groovedpasting roller 135, the collars and flanges of which are adapted to bearagainst the dollars of the grooved pasting roller 136, the collars ofwhich are in turn adaptcd to bear against the collars of the groovedpasting roller 111. The paste is contained in the box 128 and is carriedup by the roller 135 and by it placed on the roller 136 and the roller136 places it upon the roller 111 and as the label or stamp passes downbetween the roller 111 and the roller 110 the paste or glue is appliedto one side thereof in series of lines, leaving the intermediate partsof the label dry or free from paste. It will also be understood that thecollars on the roller 111 do not come opposite to or make contact withthe collars on the roller 110, but the collars on the one roller arestaggered with reference to the collars on the other roller. 1

Mounted on the box is a comb 137, the teeth of which project downwardlyinto the grooves between the collars on the roller 111. These teeth tendto strip the label from the roller so that the label cannot follow theroller around but must travel straight down to a position iuwhich itwill stand across the line of travel of the box so as to intercept thebox. The teeth of this comb occur in line with the collars on the roller116 and not the teeth'ion the comb 13'? and the collars on the roller110 project into the annular grooves on the roller 111, the collars onthe roller HOprejecting only slightly into the annular grooves of theroller 111. A slight clearance is allowed between the't-eeth of the comb137 and the collars on the roller 110. This insures better contactbetween the labeland the collars on the roller 111 than would otherwisebe possible if the collars on the roller 110 did not project into therecesses or grooves of the roller 111. Then too this arrangement of therollers insures to the label a maximum amount of paste, the excess ofwhich would be squeezed out if the label passed between solid rollers orrollers that were not grooved or between grooved rollers, the collars ofwhich come opposite to each other with or without clearance betweenthem. lVhen the label arrives into contact with the box and is presseddown thereon the excessive paste spreads out over the intermediate dryparts of the label not touched by the roller 111 and coats it so thatpractically all of the label is coated with paste on the one side and iscaused to adhere firmly to the box.

The top of the paste box is closed with a cover plate 138 which has anopening therein to receive the rollers 135 and 136, which. top has anopening therein for the introduction of paste which opening is coveredby a cover plate 139. The opening for the roller 135 is partially closedby the roller itself and by the teeth formed on the cover.

plate that engages between the collars or flanges of the roller. Ascraping plate 140 is adj ustably mounted on the cover plate and ismovable toward and away from the roller, it being held in place byscrews which pass through short slots in the plate. By this scrapingplate 140 the excess of paste is removed from the roller 135 and byadjusting it toward and away from the roller the quantity of orthickness of the film of paste left on the roller may be varied. Theforward end of the paste box is recessed to engage with pins orprojections 210 provided on the bar 32 that engages therewith. The rearof the box is recessed to receive a button 211 carried on a stem 212,mounted to turn on the cross bar 31. a handle 213 being provided on thestem to facilitate the turning thereof. By turning the handle 213 in onedirection, the paste box is engaged by the button and forced forwardinto contact with the pins and locked in place with the gear 194 in meshwith the pinion 193 by which it is driven. By turning the handle 213 inthe other direction the box may be released for removal from themachine.

Mounted on the cross bar 34- is the bracket 141 by which the rear end ofthe labeling magazine is supported, the forward end of the magazinebeing supported by the bracket 119. In this magazine is supported thelabels, the labels being carried therein on end. the magazine from whichfollower the lugs 1-13 and 144 project outwardly through a. slot on eachside of the magazine running the length thereof. Fastened to the lug 143is a cord 145 which runs forward and A follower 142 is mounted to slidein around the ulley 1 16 and then sidewise over the pul ey 147 down andaround the pulley 148 and up around the pulley 149 and t ien across tothe pulley 150 and back to the lug 144. Connected to the ulley 148 is aweight 151 by which the ollower is drawn forward and the labels are heldpressed firmly against the roller 107.

The sides of the magazine extend forward and partially overlap the endsof the feeding roller and the ends of the sucker and clamp for selectingthe labels, which clamp and sucker will presently be described.

To the back of the follower is attached a cord which passes back throughan opening at the back of the magazine and around a pulley 200 mountedon the rear of the magazine and then across to the pulley 201 and downto a treadle 202 at the side of the machine. l Vhen it is necessary toput a fresh supply of labels in the magazine the operator can press downthe treadle 202 with her foot and draw back the follower and hold itback while she uses both hands .to handle the labels and put them inplace. liVhen she releases the treadle the weight 151 will operate todraw the follower forward again and press the labels against the roller107.

By the roller 10'? the labels are fed successively from the magazinedown between the feed rollers 108 and 109. To prevent the feeding ofmore than one label at a time a selecting device is provided whichseparates the end label from the remaining labels of the magazine whichselecting device will now be described.

Mounted on the rock shaft 106 is the pneumatic sucker 152 which isintermittently rocked against the end label of the magazine upon whichthe pump 89 operates to produce the suction by which the label is drawnfirmly against the sucker after which the sucker rocks away carrying theend label with it turning the upper edge of it down to the positionshown in Fig. 16 and immediately thereafter the clamping device 153rocks forward against the upper end of the following label in themagazine and clamps all except the end label between the clamping deviceand the follower. Immediately thereafter the roller 107 starts to turnand feed the end label, that is thus released, down from the magazine,the clamping device holding the next succeedinglabel and preventing itfrom following thereafter. As soon as the roller 107 has fed the labelfar enough to insure its being caught by the rollers 108 and 109 theroller 107 stops operating.

The roller 10? is positively driven while it is turning to feed thelabel and this positive driving continues until after the label isgripped by the rollers 10S and 109afte1" which it ceases and as soon asthe positive driving of the roller is finished the roller 107 isreleased and is permitted to turn idly with the label as the label isdrawn down by the rollers 108 and 109, some of which turning may benecessary if a part of the label is still in contact with the roller107.

The gearing by which the functions of these various parts and theircoordination is securedwill now be described.

On the shaft 102 is provided an elongated gear 15% which at one endmeshes Withthe gear and at the other end meshes with the gear 155, (seeFig. 9,) the gear 154: being carried on the shaft 102 and keyed theretoand the gear 155 being carried on the shaft 103 and keyed thereto.Loosely mounted to the shaft 103 is the gear 156 to which is fastened aratchet 15.7. Mounted on the gear 155 is the pawl 158, which pawl issupported by a pin that passes through the gear 155 and on the oppositeend of which is carried a rocker arm 159 having a crank thereon with anantifriction roller 100. Journaled on the shaft 103 is a cam plate 161which cam plate is fastened to and is controlled by a lover 162 whichlever has a segmental slot 163 therein through which passes the stem ofa binding screw 164 car ried on the upright plate 81 by which screw thelever 162 may be clamped in any desired position within the limitspermitted by the length of-the segmental slot. Asthe gear 155 rotatesthe pawl and rocker arm are carried around with it and when the rockerarm passes over the raised part of the cam 161 the pawl is held out ofengagement with the ratchet wheel and the gear 156 with the ratchetWheel can remain at rest or can turn idly. On the shaft 101 whichcarries the roller 107 is keyed a pinon 165, which meshes with the gear156 so that the shaft 104; is driven by the gear 155. (See Figs. 4 and10.) hen the label is being drawn down by the rollers 108 and 109 itwill cause the roller 107 to turn and if the pawl 158 is then out ofengagement with the ratchet 157 the gear 15.6 and ratchet 157 will turnidly and as soon as the label has passed be yond the roller 107, theroller 107 and pinion 105, gear 156 and ratchet 157 will remain at restdue to the frictional engagement be tween the end label of the magazineand the roller 107. The cam 161 is shaped so as to precure asufliciently long engagement between the pawl*158 and ratchet 157 so asto secure a suflicient drive for the end label that has been selectedand the operation of the pawl and the ratchet may be advanced orretarded according to the position of the label on the box that may bedesired the preferred position being with the label lapped over the endof the box with the ends of the label equally lapped over [l'l'lfisidesof the box and by shifting the lever 162 the label may be put moreonthe top of the box or more on the bottom of thebox and by shifting thegears that drive the feed chain, so as to change the timing of the dogs75 with reference to the operation of: theroller 107 the label may beplaced wholly on to J of the box or on the bottom of the box if the boxis inverted, that is fed through the machine upside down. This timingofthe dogs 75 is secure by dropping the plate so that the gear 19 is nolonger in mesh with the gear 21 and then bringing the dogs 75 to thedesired position and then raising the plate 15 to bring the gears-intomesh a in and keep this-relation of the parts. his plate 15 can also beadjusted up or down to maintain proper. engagement of the driving gearswith the gearing of the feeding and pasting mechanism when it is raisedor lowered by the adjustment of the frame on which it is carried whichadjustment is made to accommodate the machine to boxes of diflcrentthicknesses.

A spring 166 is provided by which the antifriction roller 160 is alwaysheld in engagement with the surface of the cam 161. On the shaft 103 iskeyed the cams 107 which operate the pneumatic sucker and the cam 168which operates the clamping device.- (See Fig. 12.)

Mounted on the plate 82 is the stud 169 on which is carried a lever 170having a bell crank arm 171 on the lower end thereof, to which isconnected a tension spring 172, the upper end of which is connected to apin 173. On the lever 176 is carried an antifriction roller 171- whichbears against the earn 167, being held in engagement therewith by thespring 172. On the upper end of the lever 170 is connected a link 175,the forward end of which is connected to a crank 176 on the rock shaft106. The cam 167 is shaped and timed so as to secune the rocking of thesucker into contact with the label just at the time that the pumpoperates to secure a vacuum therein and rock away with the label whilethe pressurefoot 153, see Fig.

14, moves in back of the label until the roller 107 moves to feed thelabel. livotally mounted on the same stud is the lever 177 having a bellcrank 178 on the'lower end thereof to which is connected a. tensionspring 179, the upper end of which is fastened to a pin 173. On thelever 177 is mounted an antifriction roller 180 which bears against thecam 168, being held in'position therewith by the spring 179. To theupper end of the lever 177 is connected it link 181, the forward end ofwhich engages with the lever 182 pivotally mounted on the stud 183.Theforward end of the lever 182 engages with the link 184, the forward153 and the cam 168 is so positioned meshes with the pinion 187, by

secured the clamping or retaining devicfti shaped as to secure therocking of the retaining device against the next label in the magazmeafter the pneumatic device has moved out with the top of the last labelof the magazine. Keyed to the shaft 102 is the pinion 186 (see Fig. 12)which meshes with the pinion 187 keyed to the shaft 101, by which shaftis carried the roller 109. ()n the'shaft 100 is carried a pinion 188which which the shaft 100 is driven and with it the roller 108.

.As heretofore explained the shaft 22 ex tends outside of the plate 81and carries thereon outside of the plate the gear 21. This gear mesheswith the pinion 189 keyed to the shaft 99 (see Fig. 1), which shaft isan idle shaft and carries thereon the pinion 190 which pinion in turnmeshes with the pinion 191 on the shaft 97, (see Fig. 10) on which shaftthe grooved roller 112 is carried and by this gearing the shafts 97, 98and 101 are all driven in the same angular direction and the rollers 107and 108 are driven in the opposite direction. On the shaft 98 is alsocarried the pinion 192 which meshes with the pinion 154 (see Fig. 9) andis driven thereby and on the shaft 98 is also carried the pinion 193(see Fig. 13) which meshes with the pinion 19s on the shaft 131 andthrough this mechanism the glue rollers are driven.
